3Claims. (Cl. 16-140) This invention relates to improvements in hinges and more particularly to an improved hinge for supporting shutters adjacent to the window openings of a building.

Shutter hinges are well known in the art and have been provided in various forms. It has been found, however, that when conventional shutter hinges are used and it is desired to install storm windows, either the hinges must be removed or the storm windows must be notched to pass the hinges since the conventional hinges have portions which set inside of the face planes of the window opening.

It is among the objects of the present invention to provide an improved hinge construction, portions of which may be permanently attached to the window frame and to the shutter, in which the hinge pin is so located that the shutter will fit closely against the window frame and in line with the outer edge of the frame when closed and will have its inner edge portion substantially flush with the edge of the window opening when open, and wherein the pin and a supporting member therefor is separately removable from the remainder of the hinge to eliminate any portion of the hinge extending within the window opening. Thus, a storm window may b installed in the window opening without removing the hinge parts from the window frame and without having to notch the edges of the storm window sash to enable the window to pass an inwardly extending portion of the hinge.

Another object of the invention is the provision of an improved hinge construction which provides for an interlocking of the operating parts in order that the shutter will be maintained in the desired position, and at the same time that the shutter may be operated without the necessity of using levers and the like to release the frictionally engaged parts.

Other objects and advantages will be apparent from a consideration of the following description in conjunction with'the accompanying drawings, wherein:

Fig. l is an isometric view of a window provided with a storm window and shutters showing the application thereto of improved shutter hinges illustrative of the invention;

Fig. 2, an isometric view of a hinge butt portion adapted to be attached to the window frame;

Fig. 3, an isometric view of a hinge pin adapted to be utilized with the frame and shutter butt portions of the present invention;

. Fig. 4, an isometric view of a hinge butt portion adapted to be secured to a shutter;

Fig. 5, an isometric view showing the hinge of this invention in open position Fig. 6, an isometric view similar to Fig. 5 showing the hinge in closed position;

Fig. '7, a top plan view of the hinge pin shown in Fig. 3; and

Fig. 8, a bottom plan view of the structure shown in Fig. 4.

With continued reference to the drawings, a house wall I0 is provided with a window opening having the usual window frame H, ledge I2 and sash IS. The window is provided with shutters l4 and 15 secured to the frame H by hinges It, the illustration showing two hinges applied to each shutter. The shutter i4 is shown in open position and the shutter [5 in closed position, and a storm window sash I1 is shown in operative position in the window opening.

In order to maintain the axis of the hinges H5 in position so that the inner edge of the shutter will fit closely against the inner surface of the window frame at the edge thereof when the shutter is closed, and will be substantially in alignment with the vertical edge of the window opening when the shutter is open, it is necessary to have the common axis of the hinge pins substantially in the plane of the inner surface of the window frame. This causes a portion of the hinge structure to project within the area of the window opening so that a storm window cannot be installed without either removing the hinge butt portions secured to the window frame or providing notches or indentations in the edges of the storm window sash to pass these inwardly extending portions of the hinges. An attempt has been made to overcome this difiiculty by bending outwardly the shank of the hinge portions secured to the window frame to offset the hinge pins away from the area of the window opening. This has the result, however, of throwing the shutters outwardly relative to the window opening so that the inner edges of the shutters do not line up with the vertical edges of the Window opening when the shutters are open or, if the hinges are adjusted to accomplish this, then the shutters will not properly close with the window frame.

The improved hinge comprises a flat butt portion [8 which is set into the window frame so that its outer surface is flush therewith, and is provided with openings l9 for the reception of fasteners securing the butt portion to the window frame. A shank or body portion 20 extends outwardly from one side. of the butt portion 18 and includes a fiat surface'Zl substantially in the plane of the surface of the butt portion which is adapted to be flush with the surface of the window frame. The shank portion has a vertical opening 23 which may be of rectangular, polygonal, or other crosssection to prevent rotation of a hinge pin 26 to be received therein. A lateral aperture 24 is also provided for the reception of a locking means, such as a cotter pin.

A hinge pin 26 is provided with a lower shaft 21, of a cross-section adapted to seat in the opening 23, and an offset eccentrically disposed cylindrical upper shaft 28. The pin 26 is provided with a substantially disc-shaped portionv 29 having longitudinally extending diametrically disposed cam members 36. Each of the cam members 30 has a forward inclined surface 3| and a rearward inclined surface 32. A key member 33, which may be integral with shaft 28, is provided to serve as a stop for preventing relative swinging movement of the hinge parts beyond predetermined limits and a lateral aperture 34 is provided in the shaft 21 for the reception of a locking member or cotter pin.

A hinge butt portion 35, as shown in Fig. 4, is adapted to be set into the edge of a shutter,

such. as the shutter I4, and has a shank portion 36 extending therefrom. Openings 3? are provided for the reception. of suitable fasteners for attaching the hinge butt portion 35 to the shutter. The shank portion 36 has an upper portion which is substantially cylindrical in shape and a lower portion including a pair of diametrically disposed cam members 38 which are adapted. to ride on the cam members 36 of the hinge pin. A space 39 is provided between the cam members 38 for the reception of the key 33 on the hinge pin, it being understood that the cam, members 38 of. the shank 36 provide abutments for contacting the key at the two extreme positions of swinging movement to form a positive stop. The cam members 38 are provided with a forward inclined surface 46 and a rear inclined surface 41, in order to provide for frictional engagement with the cam members 30 of the pin 26. A bore 42 is provided in the shank for the reception of the upper shaft 28 of the hinge pin 26.

In the operation of the device it is contemplated that the butt portion l8 will be set flush in the window frame with the shank portion 26 extending outwardly, as shown in Fig. 1. The lower rectangular shaft of the pin 26 may be inserted into the rectangular bore of the shank 26 and a cotter pin inserted through the mating or aligned apertures 24 and 34 of the shank and pin in order that the pin may not be lifted out of the bore accidentally. In this position the upper cylindrical eccentrically offset portion of the pin 26 will have its axis in substantially the plane of the external surface of the window frame in order that the shutter will be supported in the proper position relative to the window frame. The butt portion 35 attached to the shuttermay be lowered down over the cylindrical portion 28 of the hinge pin with the hinge pin positioning the same by being inserted in the aperture 32 of the shank portion. In this position it is apparent. that movement of the shutter relative to. the window frame from the open position shown in Figs. 1 and will cause the cam members 38 of the shutter butt portion to ride up over the cam members 36 of the hinge pin, and that the same will come to a position of rest when the surfaces 4| of the earns 38 abut the faces 3| of the cam members 36. In this position the shutter is frictionally locked in position so that the ordinary forces of nature, such as the wind, tending to move the same will not alter its position. It is apparent, however, that an operator may easily move the shutter back to open position by a force applied thereto which will cause the surfaces 4! of the shutter shank cams to ride up on the surfaces 34 of the pin cams, until the surfaces 40 contact the surfaces 32' at which time the shutter will be securely held in open position. The key 33 effectively prevents movement of the shutter beyond open or closed position.

Whenrit is desired to install a storm window sash in a window having shutters mounted by the improved hinges, the shutters are first removed from the hinges, the pin carrying members are removed from the hinge butt portions secured to the Window frame and the storm window sash may then be inserted without providing any recesses in the sash edges and without removing the fixed portion of the hinges, since no portion of the hinge butt portion I8 facing the window opening extends into the area of the window opening.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof andth'erefore the invention is not limited by that which is shown in the drawings and described in the specification but only as indicated in the appended claims.
